I feel like this is a bit special-purpose and heavy for a GUI toolkit,
no?  What kind of dependencies would it add to gtk?  Obviously the
widget isn't very useful without an A/V framework backend, and I
wouldn't want to see gtk depend on gstreamer, xine-lib, etc.

Or maybe it could be done similar to theme engines or file system
backends: let A/V backends be installable separately without being a
hard dependency of gtk (obviously the video widget wouldn't do
much/anything without a backend installed).

Can this be implemented in GtkScale as extra API instead of adding a
new widget?

You mean sorta how YouTube does the seek bar with the little red
indicator that moves to the right as more data gets downloaded?  Yeah,
that could be pretty useful, maybe in things other than multimedia
apps.  But again, could this be implemented via extra API in an
existing widget?
